Revert "drm/radeon/kms: switch back to min->max pll post divider iteration"
commit bd6a60afeb4c9ada3ff27f1d13db1a2b5c11d8c0 upstream.
This reverts commit a6f9761743bf35b052180f4a8bdae4d2cc0465f6.
Remove this commit as it is no longer necessary. The relevant bugs
were fixed properly in:
drm/radeon/kms: hopefully fix pll issues for real (v3)
5b40ddf888398ce4cccbf3b9d0a18d90149ed7ff
drm/radeon/kms: add missing frac fb div flag for dce4+
9f4283f49f0a96a64c5a45fe56f0f8c942885eef
This commit also broke certain ~5 Mhz modes on old arcade monitors,
so reverting this commit fixes:
